As IC geometries continue to shrink and switching speeds increase, designing electromagnetic systems and printed circuit boards to meet the required signal integrity and EMC specifications has become even more challenging. A new design methodology is required. Specifically, the utilization of an electromagnetic physics-based design methodology to control the field energy in your design will be discussed. This training module will walk through the development process and provide you with guidelines for building successful, cost effective printed circuit boards. This session will, after an introduction to EM field behavior, describe several effective methods for designing the spaces which are used to direct EM fields on a PCB. Simple rules for managing these fields will be described, based on one key behavior. How fast does the switch change states? This defines the requirements for the power distribution and the geometry of the space between the output of the switch and the receiver. Several real-world examples of the use of these principles, both for designing compliant boards and for analyzing EMC failures are presented.
